Final answer:
The degree of a monomial is determined by the sum of the exponents of its variables. Each monomial listed has a degree based on the number of variables present.
Step-by-step explanation:
The degree of a monomial is the sum of the exponents of its variables. Let's determine the degree of each monomial:
- 4 has no variables, so its degree is 0.
- a. 2b has one variable, so its degree is 1.
- b. 4c has one variable, so its degree is 1.
- c. 6d has one variable, so its degree is 1.
- d. 82z has one variable, so its degree is 1.
- 4r2st3 has five variables, so its degree is 5.
- 3xyz2 has four variables, so its degree is 4.
